Electronic apparatus having lock mechanism for locking battery accommodated in battery compartment

An electronic apparatus with a lock mechanism for locking a battery in a battery compartment, with high space efficiency, even when the sizes of an apparatus body and the battery are reduced. A digital camera includes a battery compartment member formed with a battery compartment for removably accommodating a battery, a battery lid for opening and closing an insertion opening of the battery compartment, a pivot shaft for pivotally supporting the battery lid, a lock member for engaging the battery to lock the same, and an urging member for urging the battery lid in an opening direction. The lock member can move along an axis of the pivot shaft between a position for engaging the battery and a position for releasing the engagement. The urging member is disposed coaxially with the pivot shaft and urges the lock member toward the position for engaging the battery.
